Valve arrangement

Abstract

The valve arrangement comprises a predetermined number of individual valve functionalities, arranged in a manner parallel to each other. A fixed connector plate ( 3 ) has a number of sample funnel tubes ( 6 ) and output connections ( 8 ) for forward transfer of the samples arranged offset from the above. A valve plate ( 14 ) with the same number of sample loops ( 24 ) for accommodating precisely measured sample amounts may be displaced linearly with respect to the connector plate. In a first position the sample loops are connected to the sample funnel tubes and in a second position with the output connections.

1. A valve arrangement with a given number of individual valves arranged parallel to one another, comprising a fixed connector plate with the same given number of sample funnel tubes and the same given number of output connections, offset relative to the sample funnel tubes, for conveying the samples, and a valve plate provided with the same given number of sample loops for accommodating precisely measured amounts of the samples, said valve plate being capable of linear displacement between a first position, in which the sample loops are coupled to the sample funnel tubes, and a second position, in which the sample loops are coupled to the output connections. 
     
     
       2. The valve arrangement according to  claim 1 , wherein, in the first position of the valve plate, the sample loops are coupled on the output side to an overflow line. 
     
     
       3. The valve arrangement according to  claim 1 , wherein, in the second position of the valve plate, the sample loops are coupled on the input side to a solvent pressure line and at the same time the sample funnel tubes are coupled to a flushing system.
